M3452-H1600M14-R7
$17,249M3452-H1600M14-R7
The Bonitron M3452-H1600M14-R7 is a heavy-duty dynamic braking transistor built for high-power 460–480 VAC variable frequency drive systems. Its M14 open-chassis design supports up to 1600 A peak and 1200 A RMS braking current, providing the capacity needed to manage substantial regenerative loads. When rising DC bus voltage is detected, the unit switches excess energy through an external braking resistor to help prevent VFD overvoltage faults and maintain controlled motor deceleration. This configuration uses 460 VAC control power, a 750 VDC braking setpoint, and a 0.47-ohm minimum braking resistance. The standard R7 control board provides discrete control and status functions, making this model well suited for large industrial drive systems requiring dependable high-current dynamic braking.

M3452-H1600M14-R7E
$17,568M3452-H1600M14-R7E
The Bonitron M3452-H1600M14-R7E is a 1600 HP heavy-duty braking transistor designed for high-power 460–480 VAC variable frequency drive systems. Using 460 VAC control power, this M14 configuration monitors the VFD DC bus and directs regenerative energy into an external braking resistor when bus voltage rises during deceleration or overhauling operation. Rated for 1600 A peak and 1200 A RMS braking current, the unit uses a 750 VDC braking setpoint and supports a minimum braking resistance of 0.47 ohms. The R7E control option provides extended I/O for additional monitoring and system integration, making this model well suited for large industrial drives that require high-current dynamic braking, controlled stopping, and reliable protection from DC bus overvoltage faults.

M3452-H1600T10-R7
$20,449M3452-H1600T10-R7
The Bonitron M3452-H1600T10-R7 is a high-power dynamic braking transistor designed for 460–480 VAC variable frequency drive systems that experience regenerative energy during rapid stopping or overhauling operation. Using 460–480 VAC control power, this T10 configuration monitors the drive DC bus and switches excess energy to an external braking resistor when voltage reaches the 750 VDC braking threshold. Rated for 1600 A peak and 1200 A RMS braking current, the unit supports a minimum braking resistance of 0.47 ohms for demanding high-horsepower applications. The standard R7 control option provides discrete hardwired control and monitoring, making this model a practical solution for large industrial VFD systems requiring reliable braking performance and protection against DC bus overvoltage faults.

$20,766M3452-H1600T10-R7E
The Bonitron M3452-H1600T10-R7E is a heavy-duty dynamic braking transistor designed for high-power 460 VAC variable frequency drive systems. Rated for 1600 A peak and 1200 A RMS braking current, this T10 configuration helps control regenerative energy by monitoring the VFD DC bus and switching excess energy into an external braking resistor during deceleration or overhauling conditions. The result is improved control of rising DC bus voltage, helping reduce nuisance overvoltage trips and support reliable motor stopping. This model uses 460 VAC control power and supports a minimum braking resistance of 0.47 ohms. The R7E control option adds extended I/O capabilities, making this configuration well suited for large industrial drive systems requiring high-current dynamic braking and additional monitoring functionality.
